DlTCHlNG-PLOW.

SPECIFICATION forming part of Letters Patent No. 240,127, dated April 12, 1881.

Application filed February 4, 1881. (No model.)

To all whom it may concern:

Be it known that I, ALFONZO HASKINS, of Davisville, county of Yolo, and State of California, have invented an Improved Ditchiug-' Plow; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to certain improvements in that class of plows which are used for ditching or excavating purposes; and it consists in certain details of construction, as hereinafter more specifically described and claimed.

Figure l is aview of my plow. detail of construction.

A is the plow-beam, which may be constructed in any suitable manner, having the handles B and the front or colter wheel, 0, which may be adjusted up or down by means of the hinged or pivoted standards D and the curved links or arms E, as shown.

The standard F is suitably secured to the beam, and the shoe G is bolted or fixed to its foot. This shoe is of considerable length, narrow, and flat upon its bottom, so as to run upon the bottom of the trench and smooth and level it, similar to the action of a plane.

The point H is formed upon or secured to the front of a bar or plate, I, which has its upper end secured to the standard and extends down to the front of the shoe, thus forming a support for the shares J, which may be bolted or otherwise secured to it. The shares conform to the outline of this bar, and are s: Fig 21 t made narrow and flat at their lower front end. so as to receive the earth from the point H, having about the same width. This flat surface extends upward and backward, widening slightly up to the point where the shares begin to curve outward. The surface of this portion is nearly in a straight line from the point, and brings the earth up to the flaring portion of the shares, which then take it and throw it outward upon each side and entirely clear of the trench. By this means I am enabled to form trenches of any desired depth, having a perfectly smooth flat bottom, suitable for laying cement or other pipe.

This plow is especially adapted to the formation of trenches in which irrigating-pipe is laid, being formed and laid at one operation ALFQNZO HASKINS.
